netfilter: ebtables: CONFIG_COMPAT: reject trailing data after last rule
If userspace provides a rule blob with trailing data after last target,
we trigger a splat, then convert ruleset to 64bit format (with trailing
data), then pass that to do_replace_finish() which then returns -EINVAL.
Erroring out right away avoids the splat plus unneeded translation and
error unwind.
